Specification of Letters Patent.

Patented Nov. 14,1916.

Application filed Septemhr22, 1913. Serial No. 790,996.

To cZZ whom it may concern:

Be it known that I, Gnoncn MARSHALL, citizen of the United States, and residing at Wau inm, county of Fond du Lac, State of '5 Wisconsin, have invented an Improvement 'in Singeing-Machines, of Which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in sing-ring machines, and more particularly to machines for singeing hosiery of the type which comprises supporting forms which travel 'in a fixed path through the field of a singeing device, the stockings being placed upon the form prior to its entrance into the field of the singeing device. In this type of machines means have also been provided for removing'the stocking from the supporting forinafter it has been singed.

The invention is more particularly concorned with machines of the socalled Hagar type such as illustrated and described in United States Patent No. 971,427, granted September 27, 1910. In such machines the supporting forms are made to conform substantially to the segments of a cylinder, these segments being supported. upon brackets extending from the ends of radial arms carried by a rotating shaft. The singeing means comprise gas jets arranged in the superstructure of the machine in such a manner that one jet is adapted to play upon the under side of the stocking upon the form, and the other jet is caused to play downupon the outer surface of the stocking carried by the form.

In these devices the stocking or other article being singed is'removed from the support by avtraveling stripper, which is caused to follow a path. substantially con centric with the path of the supports during a portion of their rotation, ing driven at a speed in excess of that of the support. I

One of the objects of my invention is so to construct the singeing machine that the action'of the singeing means, Whether heaters, burners, or jets, will be uniform upon .both sides of the support for the article to be singed, a result which it is exceedingly difiicult to secure When gas flames are projected upon the upper and under surfaces the stripper beof the article being singed. because of the tendency of both flames to ascend.

' To attain this result, this invention contemplates arranging the support for the article to be singed in such a manner that its hroader faces shall be in planes normal to its axis of rotation, and the heating devices, burners or flames arranged preferably vertically, but in any event adjacent to and parallel with the faces of the supporting forms. By this arrangement it isfound in practice that a great saving of gas is accomplished, it requiring substantially one half the amount of gas to ope ate a machine made in accordance with this invention that it would to operate a machine of the character above described.

A further advantage accomplished in a machine made in accordance with this invention is that by reason of the smallness of the flame required, and its location, the operators face is not in danger of being burned.

Another object of this invention is to provide a stripper which will embrace or partially surround the form during a portion of its rotation, and by traveling at a greater speed than that of said form, engage the singed article on both sides of the form, thereby stripping it from the form by even pressure on both sides and avoiding stretching or mutilation of the article.

Other objects of my invention will be apparent from the following description and drawings, and will be pointed out in the appended claims. It is to be understood, however, that the drawing illustrates one of the preferred embodiments of my invention, but that it is not restrictive and that my invention comprises any means whereby the si11geing' burners are adapted to project flames equally from oppositely disposed burners upon a traveling support for the article to be singed in such a manner that the jets of flame will impingethereupon at equal angles to the vertical, y

In the drawings, Figure 1 is a side elevation of a si-ngeing machine embodying my invention; Fig. 2 's a plan View thereof; Fig. 3 is a detail view of a portion of one of the supports shown as having two vertical hydro-carbon burners, and Fig. 4 is a detail section through a support and the stripper carrier, and showing the forniof stripper.

In the drawings 1 represents the frame which may be of any construction suitable to support the operative parts of the machine.

2 is a. main-shaft journaled in the bearings 3 upon the main frame, and supports a spider 4 which is provided with a series of radial armsf), which carry-the supporting forms for the article to be singed. Each radial arm 5 is provided at its extremity with a bracket 6 which is secured thereto by suitable bolts, and is provided with an offset portion 7 which is attached at its outer end. to the supporting forms 8 for the article to be singed.

The offset portion above described isprovided in order that the article on the support may pass readily and freely between the burners, and also in order to provide room for the stripping mechanism, which will be hereafter described. The supportin g form or supports for the article comprise preferably thin arcuate members having relati ely greaterbreadth, the broad faces be ing in substantially vertical planes, so that the article when placed upon the form will be stretched or held with its greater width in substantially radial relation to the axis of rotation.

As illustrated in Fig. 1 the arcuate supporting members lie .in segments of the periphery of the circle described by the ends of the radial arms. By reason of this construction the articles are passed between the singeing flames in the direction of their length and are stretched upon the supports so that the flames play upon relatively narrow transverse surfaces. construction a relatively short burner 12 may be utilized and a more uniform singeing of the articles produced by reason of the fact that the heat of the flame can be distributed with almost exact uniformity throughout the width of the support; whereas in devices heretofore constructed, in which the supports are segments of a cylinder, the heating of the burners upon the under side is much greater than those upon the upper side. of the support; and in devices in which the supports are arranged upon vertical or radial arms the long burner required causes a greater amount of heat to be applied to the upper end of the article than at the lower end by reason of levitation caused by the successive jets.

Mounted upon the main frame 1 is a superstructure 9 which carries at itsupper end a gas pipe or' other fuel.supply 1.0, which may be mounted in any suitable support. Depending from the fuel supply 10 is a. T joint 11, which connects with prefer- ,ably verticallyarranged burners 12, 13, lo-

cated on opposite sides of the path in which the support for the article to be singed travels. Each of the burners 12, 13, is pro- By reason of thisprovided with orifices, the larger holes being near the bottom and decreasing in diameter toward the upper end of the burner. By

properly regulating the size of such orifices, an even distribution of the flamemay be had over the entire surface, especially where as I in the device disclosed herein the areas acted upon by the flames are relatively narrow.

Rotation is imparted to the shaft '2 which carries the traveling supports through a gear 14, which is rigidly attached to the shaft, and which meshes with a gear 15 mounted upon a drive shaft 16 which is journaled in suitable bearings '17, 18, on the frame. The shaft 16 is provided with the usual fast and loose pulleys l9 and 20.

In order to provide for the removal of the singed article from the form a stripping mechanism is provided which comprises an endless stripper carrier, preferably an endless chain 21, which passes around a suitable sprocket gear 22 rotatably mounted upon the shaft 2, thence over aulley 23 the superstructure 9, thence through a guide 24, which is in theform of the arc of a circle and which extends from near the top of the machine to a point somewhat below the medial portion thereof. At the termination of the guide the stripper carrier passes over a pulley 25 which is suitably journaled in a bearing 26 carriedby the members of the frame 1. The stripper carrier thence continues to the point first mentioned. The stripper carrier is provided with a stripper 27 which is mounted upon the carrier chain 21. The stripper .27 comprises a. shank portion 28 terminating in a U-shaped frame 29 which is adapted to extend around and embrace the broad sides of the support 8', and, thereby engage the singed article upon both sides in such a manner that the same will be thrust off of its support without unduly distorting or tearing the same. In-order to assure a close contact between the stripper and the support which carries the singed article the U-shaped portion 29 of the stripper is provided with an elastic facing 30, preferably of rubber, which is ada ted to press gently but firmly against the si es and edge of the support as the stripper is forced along the same.

In order that the stripper may force the singed article from its support, it is necesthe same ascends.

sary that the stripper shall travel in a path parallel with the path of said support, and at a greater relative speed. To effect this result suitable gearing 20 is provided connecting the driving shaft with the sprocket which drives the stripper carrier. This train of gearing comprises a large gear 31 mounted upon the driving shaft 16 which is adapt ed to mesh with a smaller gear 32 rotatably mounted uponthe main shaft Q and con nected with the sprocket Wheel 22 which serves to drive the carrier chain 21.

In the operation of this device the operator stands at the left of'the machine, as illustrated in Fig. 1', and applies a stocking or other article to the form as the free end of.

. is discharged from its support by the stripper 27. This stripper as before stated, is secured to the stripper carrier 21 which moves in a path concentric with the path of the supports for the article operated upon. The

stripper is, as before stated driven at a.

higher speed than that imparted to the carrier, and therefore serves to. traverse the support during a portion of the rotation of the latter. The operation of the stripper is so timed that it will engage and embrace the support in advance of the bracket 7 which supports the latter, and will pass beyond the end of the support and discharge the article therefrom about the time the free end of the support 8 reaches the horizontal plane of the axis of the machine.

It is to be understood that my invention thus described is merely illustrative and that the invention herein disclosed and described is applicable to other forms of traveling carrier, and that the burners may be located in other positions than that shown within the scope of my invention and that other means may be provided for supporting and actuating the stripper in accordance with the character of the particular machine to which the same is to be applied.

lVhile the burners may cated than in the-vertical and parallel arrangement illustrated and the advantages of the invention in its broader aspects still be secured, yet with the Hagar type of machine referred to this location is preferable. The

operator may thus stand at one side of the, machine and, readily and easily lace the stockings on the machine as the ormsascend in their travel in front of him; the

be otherwise lo singeing with the minimum amount of heat and without danger or discomfort to the operator.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
